Description

Device and method for sticking film members

The invention relates to a film component sticking device.

In the past, a variety of film member sticking devices have been proposed. One of the film member sticking devices is to peel a release film from a film member to which a peelable release film is pasted, and then stick the peeled film member to the film member. On an adherend (for example, refer to Patent Document 1).

FIG. 9 is a schematic diagram of the main parts of the thin-film member sticking device described in Patent Document 1. As shown in FIG. In addition, the "plastic film bonding apparatus" in patent document 1 is demonstrated as a "film member bonding apparatus" in this specification.

As shown in FIG. 9, the thin-film member sticking device described in Patent Document 1 includes a peeling unit 830 that peels the release film 810 from the thin-film member 820 to which the peelable release film 810 is stuck. A peeling portion 840 is disposed on the peeling unit 830, and a sharpened turn-back portion 841 is formed on a front end portion of the peeling portion 840. After the release film 810 is folded back at the peeling portion 840, the traveling direction is changed by the roller 850, and it travels in the arrow x 'direction.

When the peeling unit 830 peels the release film 810 from the film member 820, the peeling unit 830 faces the arrow x in a state where the film member 820 is adsorbed by an adsorption device (not shown) on the upper end surface of the peeling unit 830. Slide in the direction. Thereby, the release film 810 can be peeled from the film member 820.

[Patent Document 1] JP 2011-251805

In the thin-film member sticking device described in Patent Document 1, although the release film 810 can be peeled from the thin-film member 820 to which the peelable release film 810 is adhered, the thin-film member 820 of the peeled release film 810 can be peeled off. Although it adheres to a to-be-adhered member, there exists a subject which needs to improve the peeling part 840 for peeling the release film 810 from the film member 820.

That is, the folded-back portion 841 on the peeling portion 840 used in the thin-film member sticking device described in Patent Document 1 forms an acute angle, and the release film 810 is folded back at the acute-angled folded-back portion 841. Therefore, depending on the material of the release film 810, the release film 810 may be damaged or stuck due to friction, and eventually the release film may be damaged. Moreover, once the film member sticking device is used for a long period of time, the folded-back portion 841 will be worn due to friction between the film member sticking device and the release film.

Once the release film 810 is damaged or the folded-back portion 841 is worn, it adversely affects the running operation of the film member and the peeling operation of the release film.

In addition, similar problems also exist in other thin-film member sticking devices having a peeling portion 840 used in the thin-film member sticking device described in Patent Document 1.

FIG. 10 is an explanatory diagram for explaining an example of another conventional film member bonding apparatus. Hereinafter, the thin-film member sticking device described in Patent Document 1 is referred to as a “conventional first thin-film member sticking device”, and the thin-film member sticking device shown in FIG. 10 is referred to as a “conventional second thin-film member sticking device”. In addition, in FIG. 10, the peeling part used for the conventional 2nd film member sticking apparatus is simplified and shown.

As shown in FIG. 10, the conventional second film member sticking device also includes a peeling portion 930 that peels the release film 910 from the film member 920 to which the peelable release film 910 is adhered. The folded-back portion 931 on the peeling portion 930 has an acute-angled shape. After the release film 910 is folded back at the folded-back portion 931, the release film 910 travels in the arrow x direction, and a peelable release film is adhered from the release film 910. The release film 910 is peeled from the film member 920 of 910.

However, in the conventional second film member sticking device, when the release film 910 was peeled off, instead of using an adsorption device to adsorb the film member 920, the film member 920 was slightly advanced while the release film 910 was peeled. After the front end portion 920a (also sometimes referred to as the front end portion 920a) of the film member 920 in the traveling direction is brought to the pasting start end 940a of the adhered member 940, the front end portion 920a of the film member 920 is pressed by a pressing roller 950 or the like. When the table 960 is moved along the guide rail 970 in the direction of the arrow x ′, the release film folded back at the folding section 931 is stretched in the direction of the arrow x. Thereby, the film member 920 can be adhered to the adhered member 940.

In the conventional second thin-film member sticking device, the release film 910 is also folded back using the folded-back portion 931 at an acute angle. Therefore, it is the same as the conventional first thin-film member sticking device shown in FIG. In addition to the damage of the release film 910, the folded-back part 931 is worn due to the friction between the release member 910 and the film member sticking device for a long time, and finally the film member 920 travels and the release film 910 is eventually worn. The peeling operation caused adverse effects.

In order to eliminate these problems, it is conceivable not to set the folded-back portion at an acute angle, but to set the folded-back portion 931 as a folded-back portion 931a with an arc shape, as shown by the dotted frame B in FIG. 10. However, in the conventional second film member bonding apparatus, the positional relationship between the folded-back portion and the bonding start end 940a of the member 940 to be bonded is also an extremely important factor.

The reason for this is that, in the conventional second film member sticking device, when the front end portion 920a of the film member 920 after the release film 910 was peeled off by the folded-back portion 931 reached the member to be stuck, the accuracy of the arrival position was reached. There are high requirements.

That is, in the conventional second film member sticking device, the following operation is performed: the film member 920 after the release film 910 is peeled off by the folded-back portion 931 on the peeling portion 930 is on the extension line of the inclined surface 932 of the peeling portion 930 When the front end portion 920a of the thin film member 920 reaches the sticking start end 940a on the adhered member 940, the front end portion 920a of the thin film member 920 is pressed by the pressing roller 950 or the like, and the table 960 is pressed. While moving along the guide rail 970 in the direction of the arrow x ′, the release film folded back at the turning portion 931 is stretched in the direction of the arrow x.

Therefore, when the front end portion 920a of the film member 920 reaches the adhered member 940, once the accuracy of the arrival position is low, the film member 920 cannot be accurately adhered to the correct position of the adhered member 940. Specifically, for example, as shown in a dotted frame B in FIG. 10, once the folded-back portion 931 is provided as a folded-back portion 931a with an arc, the film member 920 after the release film is peeled through the folded-back portion 931a is When traveling on the extension of the inclined surface 932 of the peeling portion 930, the distance from the front end portion 920a of the film member 920 to the adhesion start end 940a of the adhered member 940 becomes longer, and the time until the adhesion start end 940a is reached May cause bending due to its own weight. Therefore, the front end portion 920a of the thin film member 920 cannot reach the sticking start end 940a of the adhered member 940 with high accuracy, and the thin film member 920 cannot be accurately adhered to the adhered member 940.

The aforementioned problem is that the front end portion 920a of the film member 920 cannot reach the adhesion start end 940a of the adhered member 940 with high accuracy, which results in the problem that the film member 920 cannot be accurately adhered to the adhered member 940. This may occur when the folded-back portion 931 is provided as a folded-back portion 931a with a circular arc, and may also occur when, for example, the folded-back portion 931 is provided as a roller (illustrated). That is, even if the folded-back portion 931 is provided as a roller, the tilt of the film member 920 after the release film 910 is peeled off from the release portion 930 is the same as when the folded-back portion 931 is provided as the folded-back portion 931a with an arc. When traveling along the extension line of the surface 932, the distance to the adhesion start end 940a of the adhered member 940 becomes longer, so that the front end portion 920a of the film member 920 cannot reach the adhesion start end 940a of the adhered member 940 with high accuracy. .

In view of the above problems, the present invention aims to provide a thin film member sticking device, so that the leading end of the film member in the direction of travel of the peeled release film reaches the sticking start end of the sticking member after the sticking start end is used as a starting point. The film member is adhered to the film adhesive surface, which can prevent the release film from being damaged or abraded at the folded-back portion, thereby reliably performing the film member's traveling operation and the release film peeling operation, and can also peel the release film. The front end of the film member in the traveling direction reaches the starting end of the adhered member accurately.

[1] The thin film member sticking device according to the first aspect of the present invention peels off the release film from a thin film member having a sticking surface on which a peelable release film is stuck. While advancing the film member, after the leading end of the film member in the traveling direction from which the release film is peeled off reaches the pasting start end of the adhered member, the pasting start end is used as a starting point to move the film member Pasting on the adhered member, wherein the thin film member sticking device includes: a table for placing the adhered member; and a thin film member supply mechanism section for peeling the release film from the thin film member, One side of the film member is supplied, and the film member is supplied so that the leading end portion of the film member in the direction of travel reaches the sticking start end of the member to be adhered, wherein the film member supply mechanism includes a peeling roller, The orientation is almost the same as the traveling direction of the film member.

Hereinafter, the thin-film member sticking devices 1 to 5 according to the first to fifth embodiments will be described in detail.

[Embodiment 1]

FIG. 1 is a diagram for explaining a film member bonding apparatus 1 according to the first embodiment. The thin-film member sticking device 1 according to the first embodiment shown in FIG. 1 is a schematic view, and therefore does not necessarily reflect the actual size. As shown in FIG. 1, the thin-film member sticking device 1 according to the first embodiment includes a table 20 for placing a glass substrate 10 as a member to be stuck, and a thin-film member supply mechanism section 100 from a polarizing film 30 as a thin-film member. (Refer to FIG. 2), while peeling the release film 40, the polarizing film 30 is advanced, and the polarizing film 30 is supplied so that the forward end portion 30a of the polarizing film 30 in the direction of advancement reaches the adhesion starting end 10a of the glass substrate 10; and The control device 200 has a control function of controlling each constituent element of the film member bonding apparatus 1 according to the first embodiment. The control function of the control device 200 will be described later.

In the thin-film member sticking device 1 according to the first embodiment, the polarizing film 30 is adhered to the glass substrate 10 by fixing the thin-film member supply mechanism unit 100 and moving the table 20 (moving along the x-axis). To explain. FIG. 1 shows a state where the table 20 has moved to a position where the operation of adhering the polarizing film 30 to the glass substrate 10 is performed.

The film member supply mechanism unit 100 includes a peeling roller 110 that peels the release film 40 from the polarizing film 30 by folding back the release film 40 in a direction almost opposite to the direction in which the polarizing film 30 travels; the release film travels The mechanism section 120 advances the release film 40 after being folded back by the peeling roller 110; The member 130 has a guide surface 131 that guides the polarizing film 30 after the release film 40 is peeled off by the peeling roller 110, and guides the polarizing film 30 in the traveling direction of the polarizing film 30 by pressing the roller 140 ( Hereinafter referred to as the front end portion 30a) When the front end portion 30a of the glass substrate 10 is reached, the front end portion 30a of the polarizing film 30 is pressed at the pasting start end 10a; ) To shoot.

As the peeling roller 110, a roller having a bearing is used. Thereby, when the release film 40 is peeled from the polarizing film 30, the release film 40 can be smoothly peeled with a small force.

In addition to the above-mentioned constituent elements, the thin-film member supply mechanism unit 100 is provided with rollers 161 and 162 for bending the polarizing film 30 (the polarizing film 30 in a state where the release film 40 is adhered) and then traveling. In addition, there are a transport mechanism section for transporting the polarizing film 30, a tension adjustment roller, and the like arranged in the middle of the travel route, but these constituent elements are not illustrated.

In FIG. 1, the polarizing film 30 (the polarizing film 30 in a state in which the release film 40 is adhered) is bent downward at a large angle through the roller 161, and then a predetermined angle is formed by the roller 162 and the xy plane. The film member sticking device 1 according to the first aspect reaches a peeling roll 110 after being bent at 30 degrees). Although the polarizing film 30 (the polarizing film 30 in a state in which the release film 40 is adhered) will travel in a downward direction or an oblique direction by the rollers 161 and 162 on the traveling route, the polarizing film 30 generally follows The x-axis is performed in the right-to-left direction (arrow x 'direction) shown in the figure. Therefore, in this specification, when describing the traveling direction of the polarizing film 30, description is made using "in the direction of the arrow x 'along the x-axis" or "right-to-left direction in the figure".

FIG. 2 is a diagram for explaining the polarizing film 30. 2 (a) is a plan view of the polarizing film 30, and FIG. 2 (b) is a cross-sectional view of the polarizing film 30. As shown in FIG. As shown in FIG. 2, the polarizing film 30 has a long sheet shape, and the long sheet-like release film 40 is affixed to the polarizing film main body 32 via an adhesive layer 34 in a peelable state. The polarizing film 30 is provided with cutouts every fixed length in a state where the release film 40 is retained, and through the cutouts, The polarizing film 30 can be made into small pieces so as to correspond to the size of each of the glass substrates 10 (see FIG. 1) as the object of adhesion. For example, when the long side (length of 1500 mm) of the glass substrate 10 is placed on the table 20 along the x-axis, the long side (length of 1490mm) is provided with cuts C1, C2,...

In the long polarizing film 30 shown in FIG. 2, when describing each polarizing film corresponding to each glass substrate 10, starting from the left in FIG. The order of 30A, the second polarizing film 30B,... Will be described. The cutouts C1, C2,... May indicate the rear end portion 30b (hereinafter simply referred to as the rear end portion) of the direction of travel of each polarizing film 30, or may indicate the front end portion 30a. For example, in the case of the first polarizing film 30A, the cutout C1 indicates the rear end portion 30b of the first polarizing film 30A, and in the case of the second polarizing film 30B, the cutout C1 indicates the front end portion 30a of the second polarizing film 30B.

Next, referring back to FIG. 1, each constituent element of the film member bonding apparatus 1 according to the first embodiment will be described in further detail.

The table 20 is capable of reciprocating in the arrow x-x 'direction along the x-axis on the guide rail 60 laid on the platform 50. In addition to being able to move back and forth along the x-axis, the table 20 can also perform position adjustment along the y-axis and angle adjustment on the xy plane. In addition, the reciprocating movement of the table 20 along the x axis, the position adjustment along the y axis, and the angle adjustment on the xy plane can be controlled by a control function provided in the control device 200. The table 20, the platform 50, and the guide rail 60 are made of metal such as iron.

The release film traveling mechanism unit 120 has a function of advancing the release film 40 that has been folded back by the peeling roller 110 in the arrow x direction. In addition, the traveling direction (arrow x direction) of the release film 40 after being folded back by the peeling roller 110 is referred to as a "release film traveling direction".

The release film traveling mechanism unit 120 includes a tension adjustment roller 125 provided on the downstream side in the traveling direction of the release film 40 after being folded back by the release roller 110; a plurality of rollers (for example, rollers 121 to 124); and a release roller 110 provided A feeding mechanism section 126 between the tension adjusting roller 125 (specifically, between the roller 122 and the roller 123); and a winding provided on the downstream side of the tension adjusting roller 125 for winding the release film 40 Roller (not shown) and the like.

The feeding mechanism section 126 has a plurality of clampers 127 for holding the release film 40, and is capable of reciprocating in the arrow x-x 'direction along the x-axis. The feeding mechanism section 126 has a function for causing the front end portion 30 a of the polarizing film 30 from which the release film 40 is peeled to reach the adhesion start end 10 a of the glass substrate 10.

This operation of the feeding mechanism section 126 is performed by a control function provided in the control device 200. In this case, the control device 200 monitors the position (position along the x-axis) of a predetermined portion (for example, the rear end portion 30b) of the polarizing film 30 based on the shooting data of the camera 150, and controls the feeding mechanism portion 126 to make the polarizing film 30 The front end portion 30 a reaches the adhesion start end 10 a of the glass substrate 10.

As an example of the control of the feeding mechanism unit 126 by the control device 200, for example, the control device 200 monitors the rear end portion of the polarizing film (first polarizing film 30A) that is the object to be pasted based on the imaging data from the camera 150. 30b (the notch C1 between the first polarizing film 30A and the second polarizing film 30B), and the feeding mechanism unit 126 is operated until the position of the rear end portion 30b (the notch C1) reaches the target position.

Specifically, the position of the rear end portion 30 b of the polarizing film 30 when the front end portion 30 a of the polarizing film 30 reaches the bonding start end 10 a of the glass substrate 10 correctly is set as a “target position” in advance, and the control device 200 is used to separate the The mold film 40 travels in the traveling direction of the release film until the position of the rear end portion 30 b of the polarizing film that is the object of adhesion reaches the target position. Thereby, the front end portion 30 a of the first polarizing film 30A can accurately reach the adhesion start end 10 a of the glass substrate 10.

Once the position of the rear end portion 30b (notch C1) of the polarizing film 30 reaches the target position, the release film 40 is released from being clamped, and the feeding mechanism portion 126 is controlled to return to the original position.

In the thin-film member sticking device 1 according to the first embodiment, the camera 150 monitors the position of the rear end portion 30b (notch C1) of the first polarizing film 30A as a sticking target. The reason for this configuration is that if the current If the front end portion 30a of the first polarizing film 30A to be adhered is monitored, the presence of members such as the pressing roller 140 (see FIG. 1) makes it difficult to secure the space required for the camera 150. . However, if sufficient space for setting up the camera 150 can be reserved, it may be provided to monitor the front end portion 30a of the first polarizing film 30A used as an adhesion target at the present stage.

Next, the guide member 130 and the pressing roller 140 will be described with reference to FIG. 3.

FIG. 3 is a diagram for explaining the guide member 130 and the pressing roller 140. Among them, Fig. 3 (a) is an enlarged view of the pressing roller 140 in Fig. 1 and a range surrounded by a dotted frame A in Fig. 1 and Fig. 3 (b) is a view from the top along the Z axis of Fig. 3 ( a) Floor plan. In FIG. 3 (b), the illustration of the pressing roller 140 in FIG. 3 (a) is omitted.

First, the guide member 130 will be described. The guide member 130 is a member for guiding the progress of the polarizing film 30 from which the release film 40 is peeled. Since FIG. 3 is a schematic view like FIG. 1, the mounting structure of the guide member 130 is omitted. The guide member 130 is mounted on a support member (not shown) that is erected on the platform 5. The support member is made of, for example, a metal such as stainless steel, and a non-adhesive surface treatment is performed on the guide surface 131 (the surface in contact with the polarizing film 30) of the guide member 130 to prevent adhesion of the adhesive. The purpose of this is that one surface of the polarizing film 30 is an adhesive surface having adhesiveness.

That is, since a peelable release film 40 is adhered to the adhesive surface of the polarizing film 30, one surface of the polarizing film 30 from which the release film 40 is peeled (the surface to which the release film 40 is adhered) has sticky Therefore, if the non-adhesive surface processing for preventing the adhesion of the adhesive is not applied to the guide surface 131 of the guide member 130, the adhesive surface of the polarizing film 30 will adhere to the guide surface 131 of the guide member 130, resulting in polarized light. The film 30 cannot smoothly travel along the guide surface 131 of the guide member 130.

The non-adhesive surface processing for preventing adhesion of the adhesive is a publicly known technique, and for example, a surface processing technology called "TOSICAL (registered trademark) S COATING" can be used. By applying such surface processing to the guide surface 131 of the guide member 130 (TOSICAL (registered trademark) S COATING film formation processing / TOSICO Corporation), the adhesive surface of the polarizing film 30 from which the release film 40 is peeled can be removed. When it adheres to the guide surface 131 of the guide member 130, the polarizing film 30 is made to travel smoothly to the adhesion start end 10a of the glass substrate 10. About TOSICAL (registered trademark) S, for example, it is suitable to use: UNA-300 series (UNA-310-X10), UNA-800 series, TS-1000 series, TS-1080 series and TS-1310 series products.

The film thickness of the TOSICAL (registered trademark) S COATING film is, for example, 1 μm to 200 μm, and preferably 3 μm to 150 μm. Before the TOSICAL (registered trademark) S COATING film is formed, an uneven structure may be formed on the guide surface 131 of the guide member 130 in advance. The average surface roughness Ra of the uneven structure in this case is preferably set in a range of 2 μm to 15 μm.

The guide member 130 is provided such that the guide surface 131 is inclined at an acute angle with respect to the glass substrate 10 while taking the front end portion of the guide member 130 as an edge. Specifically, in the film member sticking device 1 according to the first embodiment, the guide member 130 has a triangular block shape, and the front end portion 132 thereof has an acute angle.

As shown in FIG. 3 (a), the guide member 130 having such a structure is provided at a position (referred to as a vertical line L) at which the pasting start end 10a of the glass substrate 10 reaches the pressing point P passing through the pressing roller 140 (referred to as At the start position of the sticking operation), the sticking start end 10 a of the glass substrate 10 is positioned on the extension line of the guide surface 131. In addition, the guide member 130 is provided so as not to interact with the glass substrate placed on the table 20. 10 is in contact with each other (position along the z-axis), and the height difference between the front end portion 132 and the glass substrate 10 is reduced. The “pressing point P” of the pressing roller 140 refers to a point at which the pressing roller 140 applies a pressing force to the polarizing film 30 when the pressing roller 140 performs a pressing operation on the polarizing film 30.

In the thin-film member bonding apparatus 1 according to the first embodiment, the inclination of the guide surface 131, that is, the angle θ between the guide surface 131 and the xy plane (between the guide surface 131 and the glass substrate 10 placed on the table 20) The angle θ) is set to 30 degrees. In addition, it is not necessary to set the angle θ between the guide surface 131 and the glass substrate 10 to a very strict 30 degrees, as long as the front end portion 30 a of the polarizing film 30 can smoothly reach the adhesion start end 10 a of the glass substrate 10.

In addition, the guide member 130 is preferably configured to shorten the distance between the front end portion 132 of the guide member 130 and the adhesion start end 10a of the glass substrate 10 as much as possible when the adhesion start end 10a of the glass substrate 10 reaches the adhesion operation start position. Interval (interval along the x-axis) d. The interval d varies depending on the inclination angle of the guide surface 131. In the film member bonding apparatus 1 according to the first embodiment, the interval d is 15 mm.

The guide member 130 is electrically grounded. Specifically, as described above, the guide member 130 is mounted on a support member (not shown) provided vertically on the platform 50. These support members and the platform 50 are both made of metal. Therefore, the guide surface 131 passes through these support members. And the platform 50 is electrically grounded. Although the guide surface 131 of the guide member 130 is subjected to non-adhesive surface processing as described above, such surface processing does not impair the conductivity of the guide surface 131.

Since FIG. 1 is a schematic diagram showing the thin-film member sticking device 1 according to the first embodiment, the specific installation state of the platform 50 is not shown. The platform 50 is a platform installed in a state of being electrically grounded to the ground of a factory. Thereby, the guide member 130 and its guide surface 131 are electrically grounded after passing through the support member and the platform 50.

As described above, since the front end portion 132 of the guide member 130 is an edge, not only the gap between the front end portion 132 of the guide member 130 and the adhesion start end 10 a of the glass substrate 10 can be shortened as much as possible, but also as small as possible. The difference between the front end portion 132 of the guide member 130 and the adhesion start end 10 a of the glass substrate 10. In this way, it is possible to shorten the adhesion of the front end portion 30 a of the polarizing film 30 to the glass substrate 10 as compared to the case where the folded-back portion is provided with, for example, an arc-shaped folded-back portion (see dotted circle B in FIG. 10). The distance to the leading end 10a prevents the polarizing film 30 from being bent due to its own weight before reaching the sticking starting end 10a. As a result, the front end portion 30 a of the polarizing film 30 traveling on the guide surface 131 can be accurately reached the adhesion start end 10 a of the glass substrate 10. In addition, since the guide member 130 is provided such that the adhesion start end 10 a of the glass substrate 10 is located on an extension of the guide surface 131, the front end portion 30 a of the polarizing film 30 traveling on the guide surface 131 can also be made by such an arrangement. The adhesion start end 10 a of the glass substrate 10 is accurately reached.

In addition, by electrically grounding the guide member 130, even if static electricity is applied to the polarizing film 30 as a thin film member, the static electricity can be removed. By removing static electricity from the polarizing film 30, not only can it be difficult for dust or garbage to adhere to the polarizing film 30, but also when the polarizing film 30 is adhered to the glass substrate 10, the polarizing film 30 can be adhered with high accuracy. On the glass substrate 10. In addition, when the glass substrate 10 to which the polarizing film 30 is adhered is transported to the next step, the polarizing film 30 can be prevented from being transported to the next step in a state of being charged with static electricity.

Next, the pressing roller 140 will be described. As shown in FIG. 3 (a), the pressing roller 140 is a structure in which two rollers 141 and 142 having different diameters are superimposed along the vertical line L, and their respective rotation axes 141a and 142a are in the direction of the front end portion 30a of the polarizing film 30. (In the direction of the y-axis). The respective rotation shafts 141a and 142a of the two pressing rollers 141 and 142 are rotatably mounted on the pressing roller mounting member 143, respectively. The pressing roller mounting member 143 is mounted on the film member supply mechanism section 100.

Here, among the two pressing rollers 141 and 142, the pressing roller 141 on the side in contact with the polarizing film 30 is set as the first pressing roller 141, and the other pressing roller 142 is set as the second pressing roller 142. In this case, The diameter Φ1 of the first pressing roller 141 (see FIG. 3 (a)) is set smaller than the diameter Φ2 of the second pressing roller 142. In the film member bonding apparatus 1 according to the first embodiment, the diameter Φ1 of the first pressing roller 141 is approximately 10 mm. The reason for setting the first pressing roller 141 and the second pressing roller 142 in a two-stage superimposed manner and setting the diameter Φ1 of the first pressing roller 141 to be smaller than the diameter Φ2 of the second pressing roller 142 will be described later.

The pressing roller 140 (the first pressing roller 141 and the second pressing roller 142) having the above-mentioned structure can be moved up and down in the Z-axis direction (arrow z-z 'direction) along with the pressing roller mounting member 143. When the film according to the first embodiment is When the component sticking device 1 is not performing a sticking operation (referred to as a non-sticking operation for short), the pressing roller 140 is detached from the plane (xy plane) included in the glass substrate 10 placed on the table 20 (above it), and when When the thin film member sticking device 1 according to the first embodiment performs a sticking operation (referred to simply as a sticking operation), the pressing roller 140 is lowered and a pressing operation on the polarizing film 30 is performed. The ascent and descent operations of the pressing roller 140 are completed by a control function provided by the control device 200.

In addition, the reason for setting the diameter Φ1 of the first pressing roller 141 to be smaller than the diameter Φ2 of the second pressing roller 142 and superimposing the second pressing roller 142 having a larger diameter on the first pressing roller 141 is as follows.

That is, when the glass substrate 10 reaches the start position of the sticking operation, the distance d between the front end portion 132 of the guide member 130 and the sticking start end 10a of the glass substrate 10 is 15 mm as described above, so the first pressing roller 141 presses the polarizing film. In the state of 30, in order to prevent the first pressing roller 141 from contacting the guide member 130, it is necessary to set the diameter Φ1 of the first pressing roller 141 as small as possible. On the other hand, once the diameter of the first pressing roller 141 is set smaller, it will produce: The pressing roller 141 is unable to apply a uniform pressing force to the entire width direction (width along the y-axis direction) of the polarizing film 30.

Specifically, the length in the width direction (in the y-axis direction in FIG. 3) of the polarizing film 30 in FIG. 3 is approximately 890 mm. If the length of the polarizing film 30 in the width direction (in the y-axis direction in FIG. 3) is greater than 890 mm, the length of the first pressing roller 141 along the rotation axis 141a (length along the y-axis) also becomes longer. At this time, the diameter Φ1 of the first pressing roller 141 becomes smaller than the length of the first pressing roller 141 along the rotation axis 141a, which may easily cause the first pressing roller 141 to bend, and once the first pressing roller 141 is generated Bending, it is impossible to apply a uniform pressing force in the entire width direction. Therefore, while the diameter Φ1 of the first pressing roller 141 is set as small as possible, a second pressing roller 142 having a larger diameter is superimposed on the first pressing roller 141 to make the pressing force at the pressing point P It is uniformly distributed over the entire width direction of the polarizing film 30.

By setting the pressing roller 140 to the above structure, even when the distance d between the front end portion 132 of the guide member 130 and the adhesion starting end 10a of the glass substrate 10 is only 15 mm, the first pressing roller 141 can be used. With the stage not in contact with the guide member 130, the polarizing film 30 is surely pressed. In addition, the second pressing roller 142 can also prevent the first pressing roller 141 from being bent, thereby helping the first pressing roller 141 to press the entire width direction of the polarizing film 30 with a uniform pressing force. In this manner, the second pressing roller 142 functions as an auxiliary roller that assists the pressing of the first pressing roller 141.

Next, the operation of the thin-film member sticking device 1 according to the first embodiment (in particular, the sticking operation of the polarizing film 30) will be described.

FIG. 4 is a diagram for explaining a sticking operation of the polarizing film 30 in the thin-film member sticking device 1 according to the first embodiment. Among them, Fig. 4 (a) shows the state before the sticking operation is started. Here, this state is used as the initial state. In this initial state, the table 20 is positioned more than the pressing roller 140 (first pressing The pressing roller 141 and the second pressing roller 142) are closer to the left position (START position) in the figure. In the initial state, the glass substrate 10 (the first glass substrate 10) as the object to be adhered at this time is placed on a predetermined position on the table 20. In addition, the amount of movement of the table 20 from the starting position along the x-axis, the position along the y-axis, and the angle (angle on the plane) around the z-axis have been appropriately adjusted.

A leading end portion (not shown) on the winding side of the release film 40 is connected to a winding roller (not shown) for winding the release film, and at this time, a polarizing film (first polarizing film) to be adhered. The leading end portion 30a of 30A) has reached the peeling roller 110. In this initial state, the pressing roller 140 (the first pressing roller 141 and the second pressing roller 142) is separated from (located above) the plane (xy plane) included in the glass substrate 10 placed on the table 20.

In the initial state shown in FIG. 4 (a), the step of moving the table 20 is performed first. That is, the control device 200 controls the table 20 to travel in a right direction (arrow x direction) along the x axis by a predetermined amount of movement. As a result, the table 20 is moved to the position shown in FIG. 4 (b) (the sticking operation start position). Specifically, the control device 200 controls the table 20 to travel in the right direction along the x-axis so that the sticking start end 10 a of the glass substrate 10 reaches a position facing the pressing point P of the pressing roller 140.

Once the table 20 is moved to the start position of the sticking operation shown in FIG. 4 (b), the sticking of the front end portion 30a of the polarizing film 30 after the release film 40 is peeled off by the peeling roller 110 to the glass substrate 10 Steps at the beginning 10a. That is, the control device 200 controls the feeding mechanism section 126 so that the polarizing film 30 reaches the sticking start end 10 a of the glass substrate 10 (thin film member supply control). Thereby, the feeding mechanism part 126 clamps the release film 40 by the holder 127, and makes this release film 40 advance to the release film advance direction (arrow x direction of a figure) according to a predetermined movement amount.

After the release film 40 is advanced in the direction of the release film by a predetermined amount of movement by the feeding mechanism section 126, the release film 40 is peeled from the first polarizing film 30A by the peeling roller 110, and then peeled. The first polarizing film 30A separated from the release film 40 travels along the guide surface 131 of the guide member 130, and then, the front end portion 30a of the first polarizing film 30A reaches the adhesion start end 10a of the first glass substrate 10 (refer to 4 (b)).

At this time, the control of the feeding mechanism section 126 by the control device 200 is performed based on the image data captured by the camera 150. As an example of the control performed by the control device 200 on the feeding mechanism section 126, as described above, the control device 200 monitors the rear of the polarizing film (the first polarizing film 30A) that is the object to be pasted based on the imaging data from the camera 150. The position of the end portion 30b (notch C1), and the feeding mechanism portion 126 is operated until the position of the rear end portion 30b (notch C1) reaches the target position. As a result, the front end portion 30 a of the first polarizing film 30A reaches the adhesion start end 10 a of the first glass substrate 10. As such, once the front end portion 30 a of the first polarizing film 30A reaches the adhesion start end 10 a of the first glass substrate 10, the control device 200 controls the feeding mechanism portion 126 to release the clamping of the release film 40. Then, the feeding mechanism unit 126 returns to the position at the initial state.

Once the feeding mechanism unit 126 advances the release film 40 in the direction of the release film, the tension adjustment roller 125 will move from the position shown by the dotted line (the tension in FIG. 4 (a), for example, as shown in FIG. 4 (b)). The position of the adjustment roller 125) performs the lowering operation in accordance with the amount of movement of the feeding mechanism section 126. By providing the tension adjustment roller 125, the polarizing film 30 by the feeding mechanism unit 126 can be supplied without the need to wind the release film 40 by the winding roller (not shown). In the case of synchronization, each operation is performed independently of each other. It is only necessary to perform the winding operation of the release film 40 by a winding roller (not shown) when the amount of drop of the tension adjustment roller 125 reaches a predetermined amount. Once the winding roller (not shown) starts the winding operation of the release film 40, the tension adjustment roller 125 returns to the original position (for example, the position shown in FIG. 4 (a)).

When the release film 40 is advanced toward the release film traveling direction by the feeding mechanism portion 126, the progress of the release film 40 is folded back by the peeling roller 110, so that not only friction on the surface of the release film 40 can be caused. In this case, breakage of the release film 40 is prevented, and abrasion of the folded-back portion (the peeling roller 110) can also be prevented.

That is, in the thin-film member sticking device 1 according to the first embodiment, a folded-back portion for peeling the release film 40 from the polarizing film 30 is provided as a roller (peeling roller 110), and the peeling roller 110 is used to make the The release film 40 travels after being folded back, thereby peeling the release film 40 from the polarizing film 30. Thereby, when the release film 40 is peeled from the polarizing film 30, it is possible to prevent the release film 40 from being damaged and to prevent abrasion of the folded-back portion (the peeling roller 110).

In addition, since the non-adhesive surface processing for preventing the adhesion of the adhesive is applied to the guide surface 131 of the guide member 130, when the polarizing film 30 with the release film 40 peeled travels on the guide surface 131 of the guide member 130, When the adhesive surface of the polarizing film 30 from which the release film 40 is peeled off does not adhere to the guide surface 131 of the guide member 130, the polarizing film 30 is allowed to travel smoothly.

Once the front end portion 30a of the first polarizing film 30A reaches the pasting start end 10a of the glass substrate 10, a step of moving (falling) the pressing roller 140 is performed, and the front end portion 30a of the polarizing film 30 is pressed by the pressing roller 140 to The glass substrate 10 is adhered to the starting end 10a. Thereby, after the pressing roller 140 (the first pressing roller 141 and the second pressing roller 142) is lowered, the pressing point P of the first pressing roller 141 presses the front end portion 30 a of the polarizing film 30 against the glass substrate 10. On the start end 10a (see FIG. 4 (c)). Thereby, the first polarizing film 30A is positioned on the pasting start end 10 a of the glass substrate 10. At this time, the second pressing roller 142 is in a state of pressing the first pressing roller 141.

Next, starting from the state shown in FIG. 4 (c) (a state where the front end portion 30a of the polarizing film 30 is pressed against the pasting start end 10a of the glass substrate 10), a step of moving the table 20 is performed, so that The polarizing film 30 is adhered to the glass substrate 10 starting from the pasting start end 10 a of the glass substrate 10. That is, starting from the state shown in FIG. 4 (c), the table 20 is moved along the x-axis in the direction of the arrow x ′ (left direction in the figure), thereby moving the first glass substrate 10 The sticking start end 10a is used as a starting point for sticking. At this time, since the pressing roller 140 is maintained in a state of pressing the first polarizing film 30A, when the table 20 moves in the direction of the arrow x ′ (left direction in the illustration), the first pressing roller 141 is smooth. Rotating clockwise, while pressing the second pressing roller 142 counterclockwise, the first polarizing film 30A is pressed against the glass substrate 10.

When performing the sticking operation shown in FIG. 4 (d), a fixed tension from the tension adjustment roller 125 is always applied to the release film 40. Therefore, during the pasting operation of the first polarizing film 30A, the tension adjusting roller 125 is further lowered from the dotted line position in FIG. 4 (d), for example, so that the release film 40 is lifted from the first polarizing film 30A. Peel off. In this case, it is sufficient to set the winding operation of the release film 40 by a winding roller (not shown) to start the winding operation when the amount of drop of the tension adjustment roller 125 reaches a predetermined amount.

By providing such a tension adjustment roller 125, it is possible to independently perform the sticking operation without synchronizing the movement operation of the table 20 with the winding operation of the release film 40 by the winding roller. To do their homework.

In addition, even during the above-mentioned sticking operation, since the release film 40 travels after being folded back by the peeling roller 110, the surface of the release film 40 does not cause friction, thereby preventing breakage of the release film 40. In this way, it is possible to prevent abrasion of the peeling portion (peeling roller 110) while preventing abrasion of the folded-back portion (peeling roller 110).

When the table 20 moves further from the state shown in Fig. 4 (d) in the direction of arrow x ', it returns to the position shown in Fig. 4 (a) (the same position as in the initial state). Thereby, the first polarizing film 30A The pasting step with respect to the first glass substrate 10 is completed. Next, a step of attaching a polarizing film (second polarizing film 30B) to a next glass substrate (second glass substrate 10) will be performed. When performing the pasting step of pasting the second polarizing film 30B on the second glass substrate 10, the first glass substrate 10 that has completed the pasting step of the first polarizing film 30A is removed from the table 20, and then the first After the two glass substrates 10 are placed on the table 20, the steps shown in Figs. 4 (a) to 4 (d) are performed. By repeating these steps, a polarizing film can be sequentially adhered to each glass substrate.

Traveling operation and peeling operation of the release film 40. In addition, since the peeling roller 110 has a bearing, the rotation of the roller becomes smooth, and when the release film 40 is peeled from the polarizing film 30, the peeling film 40 can be smoothly peeled with a small force, and It is also possible to make the release film 40 travel more smoothly after being folded back.

In the thin film member sticking device and method according to the first embodiment.

According to the guide member 130 according to the first embodiment, since the guide surface has conductivity, the guide member 130 can be applied to the thin-film member bonding apparatus and method according to the first embodiment.

According to the thin film member bonding apparatus 1 according to the first embodiment, the static electricity removing member 190 having the above structure can remove static electricity that may be attached to the adhesive surface of the thin film member 30 when the release film 40 is peeled from the thin film member 30. Therefore, not only can it be difficult for dust or garbage to adhere to the film member 30, but also the film member 30 can be adhered to the adhered member 10 with high accuracy.
